The way I handle this is by throwing exceptions in my code. So let's say that there is a db connection/query failure for whatever reason. Instead of using query() or die() which is not user friendly, I throw an exception which bubbles up. Once it hits the top then I can catch it, log it accordingly, and show the user a friendlier error page saying Oops! With an exception you get exactly what you want, a full-blown stack trace complete with paths, line numbers etc. You also get the ability to be graceful about what you show to the end user. ...but I have the feeling that you're already dealing with a situation in lots of existing code. Perhaps you could combine some suggestions in this thread and replace your die/exit statements with a custom function which logs a debug_backtrace() and then really dies, but gracefully of course. :) As an aside, if I were to see some jibberish about a query and line numbers when I click a link I'd leave that site. (And for the archives) It is a security vuln to show full file paths to an end user. If someone is tampering with your system we shouldn't give them any more information than they can already get.
